Vulnerability: buffer overflows in minires library
OpenPKG Specific: no

Affected Releases: Affected Packages: Corrected Packages:
OpenPKG CURRENT <= dhcpd-3.0.1rc10-20021108 >= dhcpd-3.0.1rc11-20030116

Description:
According to CERT advisory CA-2003-01 [0] a buffer overflow exists in
the minires library embedded in ISC DHCPD versions 3.0 through
3.0.1RC10 [1]. The Common Vulnerabilities and Exposures (CVE) project
assigned the id CAN-2003-0026 [2] to the problem.

Please check whether you are affected by running "<prefix>/bin/rpm
-q dhcpd". If you have the "dhcpd" package installed and its version
is affected (see above), we recommend that you immediately upgrade
it (see Solution). [3][4]

Solution:
Select the updated source RPM appropriate for your OpenPKG release
[5][6], fetch it from the OpenPKG FTP service [7][8] or a mirror
location, verify its integrity [9], build a corresponding binary RPM
from it [3] and update your OpenPKG installation by applying the binary
RPM [4]. For the current release OpenPKG 1.1, perform the following
operations to permanently fix the security problem (for other releases
adjust accordingly).

$ ftp ftp.openpkg.org
ftp> bin
ftp> cd release/1.1/UPD
ftp> get dhcpd-3.0.1rc9-1.1.1.src.rpm
ftp> bye
$ <prefix>/bin/rpm -v --checksig dhcpd-3.0.1rc9-1.1.1.src.rpm
$ <prefix>/bin/rpm --rebuild dhcpd-3.0.1rc9-1.1.1.src.rpm
$ su -
# <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/dhcpd-3.0.1rc9-1.1.1.*.rpm
